I think you've got the top end covered!
I haven't got any idea on what a valve job goes for, but have heard the gasket, cam seal, new reservoir, flush, and valve guides/seals goes for about a grand.
If the valves are fine I wouldn't mess with them. But I'd sure be tempted to have the cam and all it's bits measured for specification tolerances as long as they're out there and available to do so. If the cam/followers/valves/springs/journals, etc., are all within spec why bother? The three or four hours of shop time to do the "blueprinting" would be worth the peace of mind I'd think, rather than spending the money on a valve job that might not be necessary.
Just my NSHO-
